It was supposed to be the one speed limit you cannot break. But scientists claim to have demonstrated there is the possibility of travel faster than the speed of light. picked by AutumnLotus 2 years ago

Future generations could be travelling across the universe faster than the speed of light, without breaking any astronomical road rules, by manipulating extra dimensions of space and time, according to two US physicists. picked by AutumnLotus 1 year ago

Research led by the University of Warwick has found a way to use doughnut shaped by-products of quantum dots to slow and even freeze light, opening up a wide range of possibilities from reliable and effective light based computing to the possibility of "slow glass". picked by AutumnLotus 9 months ago

As soon as you are born, you are influencing light. From the day of your birth, you can see how many stars that light has reached. Works only on stars up to 50 light years away. picked by Moe 2 years ago

A glowing plaster that can patch up wounds AND destroy skin cancer cells by zapping them with light, has been unveiled by British scientists.

The strip of bendy plastic is embedded with light-emitting diodes that blast a high-powered of beam of red light onto tumours. picked by AutumnLotus 7 months ago

Einstein realised that the speed of light was one of the defining measures of the Universe. Remember E=mc2, the beautiful little formula that wrapped up the theory of relativity? Well ‘c’ is the speed of light. And you can measure it. All you need is a microwave, a ruler and a bar of chocolate (and maybe a calculator). picked by tchengrox 2 years ago

Remember the good old days when you could count on death, taxes and the speed of light. Well we still have death and taxes. Harvard physicist slows and stops light. picked by pulsisx 2 years ago

Science knows you can move a solid with the heat generated from a light source. This discovery shows that light actually exerts a physical pressure capable of moving solid matter. picked by BrownTrout 3 years ago

Jetlag need never again be a problem, according to two scientists from Boston's Brigham and Women's Hospital. All you need is an understanding of your circadian cycle, a strong light, and plenty of spare time. picked by suebe 4 months ago

Scientists at the University of St Andrews have used lasers to simulate a black hole in their laboratory. Professor Ulf Leonhardt and Dr Friedrich König used intense light pulses to create an artificial `event horizon' - the defining feature of a black hole known as `the point of no return'. The development may allow researchers to test Professor Stephen Hawking's theory that black holes are... read full post picked by AutumnLotus 2 years ago

Light graffiti is uniquely ephemeral and inextricably intertwined with the art of photography, sometimes even invisible to the naked eye and apparent only when captured on film. picked by Bornbad 12 months ago

During the next few weeks on some clear moonless early morning, if you are fortunate to be far from any haze and bright lights, keep a close watch on the eastern horizon about two hours before sunrise. If you're lucky you might catch a glimpse of a ghostly column of light extending upward into the sky. picked by AutumnLotus 1 year ago

In the era of 24/7 artificial light, real darkness is hard to find. But not only stargazers are affected -- light pollution also threatens animals and even entire ecosystems.
A small drama unfolds in the skies over Germany and other industrialized countries every evening. The sun sets, and yet it remains light -- so light, in fact, that one can hardly see anything. picked by Bingo 4 months ago

Using LED glow sticks, flashlights, even fireworks, combined with time-lapse photography, light graffiti artists create a unique tagging that wraps around objects dimensionally, allowing them to tag in a way they'd never be able to with spray paint. picked by Mershaullk 2 years ago

Two papers, from teams led by Xiang Zhang at the University of California, Berkeley, this week report on new nanomaterials, which have been especially designed to bend light the wrong way. By reversing refraction, they can in principle make objects invisible to the wavelengths of light we use to see. picked by ceflory 1 year ago

In a quantum mechanical sleight of hand, Harvard physicists have shown that they can not only bring a pulse of light, the fleetest of nature’s particles, to a complete halt, but also resuscitate the light at a different location and let it continue on its way. picked by Bornbad 3 years ago
